Correspondence in value orientation between parents and their offspring may be due to actual transmission processes between generations, but it may also be due to influences from the general value context in society that are common to parents and their offspring. This common value context is referred to as Zeitgeist. The present study deals with one family relationship value (i.e., parents’ and adolescents’ obligations toward the family). Participants were 1,252 immigrant and 726 national adolescent–parent dyads from 10 Western countries. There were significant relationships between the value placed on family obligations among parents and offspring, and these were independent of gender. Zeitgeist effects, both intergenerational and intragenerational, were found. The strength of these Zeitgeist effects depended on the basis for defining Zeitgeist, either a person’s own ethnic group or the wider community including both nationals and immigrants. For explaining national adolescents’ acceptance of their family obligations, both the ethnic and the national Zeitgeist played a role, whereas in the immigrant groups only the ethnic Zeitgeist played a significant role. In short, in an immigration context it makes sense to distinguish the influence of a person’s own ethnic group from the influence of the wider community, including other ethnic groups. Explanations are suggested and implications are discussed.

Structured analytic techniques (SATs) are intended to improve intelligence analysis by checking the two canonical sources of error: systematic biases and random noise. Although both goals are achievable, no one knows how close the current generation of SATs comes to achieving either of them. We identify two root problems: (1) SATs treat bipolar biases as unipolar. As a result, we lack metrics for gauging possible over-shooting—and have no way of knowing when SATs that focus on suppressing one bias (e.g., over-confidence) are triggering the opposing bias (e.g., under-confidence); (2) SATs tacitly assume that problem decomposition (e.g., breaking reasoning into rows and columns of matrices corresponding to hypotheses and evidence) is a sound means of reducing noise in assessments. But no one has ever actually tested whether decomposition is adding or subtracting noise from the analytic process—and there are good reasons for suspecting that decomposition will, on balance, degrade the reliability of analytic judgment. The central shortcoming is that SATs have not been subject to sustained scientific of the sort that could reveal when they are helping or harming the cause of delivering accurate assessments of the world to the policy community.  相似文献

Aviation expansion and the construction of a third runway at Heathrow airport is firmly back on the political agenda. Yet, the stark fact remains that a growing list of British governments has been unable to engineer a partial or temporary policy settlement in aviation. In exploring the challenges of reaching such a settlement, this article characterises the shifting and contested political and policy contexts of UK aviation. It begins by exploring the ‘wicked issue’ of aviation expansion before foregrounding how the politics of air travel is riven by competing policy frames, fragmented governance and the absence of gatekeepers. It argues that the Davies Commission and its efforts to remove aviation from the domain of partisan politics provided little more than a temporary respite for government. It thus concludes by questioning whether the May government's expansion proposals will succeed this time around, outlining how the contributions in this collection address the themes and issues of this overriding policy puzzle.  相似文献

Since the 1980s the Scottish National Party has presented its political project in progressive terms, but this created a twin dilemma: in order to achieve independence, the SNP needed to win political power, and in order to achieve political power it had to win an election, and orthodoxy dictated that winning elections in Scotland involved a centre‐left platform. But the two have often been in conflict, as is clear as the SNP approaches its tenth anniversary in devolved government and agitates for another referendum.  相似文献

In federal systems, both state governments and firms have incentives to strategically locate polluting facilities where the environmental and health consequences will be borne as much as possible by residents of other jurisdictions. We analyze air polluter location in the United States using a spatial point pattern model, which models where events occur in latitude and longitude. Our analyses indicate that major air polluters are significantly more likely to be located near a state's downwind border than a control group of other industrial facilities, results that are robust to a wide variety of model specifications and measurement strategies. This effect is particularly pronounced for facilities with toxic air emissions. The observed pattern of polluter location varies systematically across states and time in ways that suggest it is responsive to public policy at both the national and state levels.  相似文献

Interest groups seek to influence public policy. Business associations specifically seek to influence policy related to the environment in which their members operate, with the intention of making it easier for the members, and the wider private sector, to “do business.” Scholars question whether interest groups are influential and, if so, the degree to which their activity influences public policy. Even if they do influence public policy at the margins, it is questionable how effective they are in influencing legislation. As a result, there is little exploration of the factors that may determine whether business membership organizations (BMOs) are likely to be successful. This paper explores the efforts of two BMOs in Kenya to influence legislation: In one case, the BMO persuaded the government to introduce legislation to regulate an activity that had previously not been subject to legislation; in the other, a BMO sought to persuade the government to amend its own proposals to replace existing legislation with new legislation. In both cases, we find evidence that the BMO was successful, though one BMO was significantly more successful than the other. We review the factors perceived by the BMOs to have led to their success. Neither was in a position to rely on economic or other power to strong‐arm the government. Both followed a predominantly insider strategy though with occasional media back‐up. Both were successful on the more “technical” issues. Key factors include the use of a champion, engaging across government, supplying information, and providing evidence and good argumentation.  相似文献

The complexity of decentralized regulatory contexts can threaten program fidelity, particularly if it results in divergence between program goals and the intents of regulatory inspectors. This paper investigates how inspectors negotiate the conflicting demands of a decentralized program by examining how they perceive their regulatory roles – the primary responsibilities that inspectors ascribe to their functions and the entities to which they feel responsible – and how these role orientations are related to inspectors' attitudes toward the use of discretion. The study findings indicate that in the decentralized administration of United States organic food regulations, inspectors experience multiple, and sometimes conflicting, role orientations. The presence of multiple role orientations, however, does not seem to affect how inspectors approach their responsibilities. The combined strengths of quantitative and qualitative data are leveraged to offer explanations for the study findings and identify avenues for future research.  相似文献
